The latest edition of English Heritage's 'Current Archaeology' mentions something we ought to have known about earlier. This is the Teardrop site in Woolwich, and adjacent to the ferry.
They describe how 'one of the largest sections in London' was cut through a ditch and discovered that the ditch was probably Iron Age in origin and is thought to have enclosed a trading area (I think that means some sort of wharf). They also discovered five pottery kilns - does this also link with the well known kiln now languishing outside the Heritage Centre in its box?? Two of the kilns were 13th/14th century and used for London Ware production - the only such site ever found.
I have written to the team and hope to get more information.
Elsewhere in this edition is a note about Seager's Distillery at Deptford Bridge - which of course was described at the last GIHS meeting by Duncan Hawkins (thank you Duncan). They describe however, for those of you who weren't there, the remains of an 18th century sugar refinery, stonemasons cottages and of course the 19th century gin distillery and a late 19th century iron works.
